Traditional Buddhism did not fare well during the Momoyama and Tokugawa ages: the militaristic Buddhist strongholds were either put to rout or destroyed entirely during the Momoyama, and Confucianism had considerably more influence under the Tokugawa than did Buddhism. The great upsurge of Buddhism with its fiery teachers and believing shoguns was over, as the faith settled into empty ritual and a decidedly secondary station in a basically secular state. The only Buddhist sect demonstrating any vigor at all was Zen. The brief flourishing of Zen during the Tokugawa era was actually a revival, for the faith had become static and uninspired during the years of Nobunaga and Hideyoshi. The formalized practice of Zen at the end of the seventeenth century was described by a visiting Jesuit Father: _The solitary philosophers of the Zenshu sect, who dwell in their retreats in the wilderness, [do not] philosophize with the help of books and treatises written by illustrious masters and philosophers as do the members of the other sects of the Indian gymnosophists. Instead they give themselves up to contemplating the things of nature, despising and abandoning worldly things; they mortify their passions by certain enigmatic and figurative meditations and considerations [koan] which guide them on their way at the beginning. . . . [s]o the vocation of these philosophers is not to contend or dispute with another with arguments, but they leave everything to the contemplation of each one so that by himself he may attain the goal by using these principles, and thus they do not teach disciples.1 _ The good Father was describing a Zen faith that had become a set piece, devoid of controversy but also devoid of life. The man who brought Zen out of its slumber and restored its vigor was the mystic Hakuin (1685-1768), who revived the _koan _school of Rinzai and produced the most famous _koan_ of all times: "You know the sound of two hands clapping; what is the sound of one hand clapping?" Hakuin gave a new, mystical dimension to the Rinzai school of Zen, even as Hui-neng created nonintellectual Chinese Ch'an Buddhism out of the founding ideas of Bodhidharma. Hakuin was also a poet, a painter, and the author of many commentaries on the _sutras_. Yet even when he enjoyed national fame, he never lost his modesty or his desire for enlightenment.
